Basic Cleanup: The Easiest Ways to Instantly Save Space

To keep your PC free from daily maintenance and save space, be sure to adopt these 3 basic habits:

• Storage Sense: Let Windows automatically delete junk files.
• Temp Files: Manually clean the %temp% folder every week.
• Downloads & Bin: Keep the Recycle Bin empty by deleting unnecessary installers and old files.

Method 1: Turn On Storage Sense (Auto-Cleanup)

Windows 11’s Storage Sense is a smart feature that automatically deletes unnecessary junk and temporary files from your PC. To enable it:

• Press Windows + I on your keyboard to open Settings. Then, go to System and select Storage. Turn the ‘Storage Sense’ toggle on.

• You can also click on it to customize how often Windows automatically cleans up, such as every month or when storage is low.

Method 2: Safely Delete Temporary Files

Whenever you run an app or browse the internet, Windows creates some temporary files. If you want to manually delete temporary files in Windows 11, there are two ways to do it:

• Through Settings: First, go to Settings, then System, then Storage, and then Temporary Files. Here, Windows will automatically scan and select files that are no longer needed, such as DirectX Shader Cache, Delivery Optimization Files, etc. Select them and click ‘Remove files’.

• Via the Run Command: For this, press Windows + R on your keyboard, type %temp% in the box, and press Enter. A folder will open. Then, press Ctrl + A to select all the files and press Shift + Delete to delete them all at once. For any files that cannot be deleted, select ‘Skip’.

Method 3: Empty the Recycle Bin & Downloads Folder

We often delete files from our PC or laptop, but they aren’t actually removed from the computer; they just go into the Recycle Bin.

• To do this, right-click the Recycle Bin icon on your Desktop and select “Empty Recycle Bin” to delete everything at once. This single step can often recover 5-10 GB of storage.
• Also, check your Downloads folder. Delete old software installers (.exe files), PDFs, and ZIP files that you no longer need.

Advanced Cleanup: Remove Large Files and Unwanted Apps

If a basic cleanup doesn’t do the trick, you can easily fix major space problems with these advanced methods:

• Uninstall Apps: Remove heavy and unused software from your system.
• Find Large Files: In File Explorer, search for files larger than 1 GB to locate hidden heavy files.
• Move to Cloud/Drive: Transfer your videos and large data to an external SSD or OneDrive.

Method 4: Uninstall Unused Applications

On everyone’s PC, there are some apps or games that we haven’t opened for months. These wasteful apps consume background memory and storage. To delete them:

• Go to Settings, then Apps, then Installed Apps, and sort this list by “Size (Large to Small).”
• This will bring the largest apps to the top. For the apps or games you don’t use, click the 3 dots next to them and select “Uninstall.”

Method 5: Find and Delete Large Files

Often, we save large movies or project files in a folder and then forget about them, wondering how to increase disk space in Windows 11. There’s a smart way to find these hidden files. To do so, follow the steps below:

• Open your File Explorer (This PC). Then, click in the Search bar at the top right corner and type: size:>1GB. If you want, you can also type 500MB instead of 1GB.
• Windows will now search your entire PC for all files larger than 1GB. Carefully review them and permanently delete any unwanted files by pressing Shift + Delete.

Method 6: Move Files to External Storage or Cloud

If you have important documents, videos, or photos that you can’t delete, the best way to fix low disk space is to move them off the C: Drive.

• External Storage: Move your heavy files to an external hard drive (HDD) or a USB flash drive.
• Cloud Storage: You can use Google Drive or Microsoft OneDrive to upload your data to the cloud, which will completely free up your local PC storage.

Deep System Cleanup: Delete Hidden Space Wasters

To reclaim your system’s deeply hidden storage, you can follow these 3 advanced steps:

• Remove Windows.old: Permanently delete the backup files of the old OS update from your storage settings.
• Clear Browser Cache: Remove months-old cached images and cookies from Google Chrome and Edge.
• Disable Hibernation: Type powercfg -h off in the Command Prompt, delete the hiberfil.sys file, and save GBs of space on your PC.

Method 7: Remove Previous Windows Installation (Windows.old)

When you upgrade your PC from Windows 10 to 11 or install a major update, Windows creates a backup of the old system called the Windows.old folder. This folder can easily take up 15 GB to 30 GB of space on your PC or laptop!

If your new update is working fine and you don’t want to go back to the old version, then be sure to use this process to remove the Windows.old folder. You can follow the steps given below for this:

• First, go to Settings, then System, then Storage, and then Temporary Files.
• In the list, find “Previous Windows Installation(s)” and check it. Then click ‘Remove files’.
• This one click will significantly solve your Windows 11 disk space problem.

Method 8: Clear Browser Cache (Chrome, Edge)

We use the internet daily, and our browsers like Chrome, Edge, or Firefox save images and data in a ‘cache’ to load websites faster. After months, this cache can grow to several GBs.

• To do this, open your browser and press Ctrl + Shift + Delete at the same time. Then, select “All time” in the time range. Check the box for “Cached images and files” and click the Clear Data button. You can also untick the cookies option if you don’t want to be logged out of your browser.

Method 9: Disable Hibernation (Advanced CMD Tweak)

If you don’t use the ‘Hibernate’ feature on your laptop, you can easily save 3-5 GB of space by deleting a hidden file named ‘hiberfil.sys’.

• Go to the Start menu and search for CMD in the search bar, then right-click on it and click ‘Run as administrator’ to open it.
• Then, when the black screen (Command Prompt) opens, type: powercfg -h off and press Enter. That’s it, hibernation is disabled and the system has automatically deleted that large hidden file.
